Improvement in buttons



UNITED STATES PATENT OEEIoEo CARL BRANDT, OF GOERSNITZ, GERMANY.

IMPROVEMENT IN BUTTONS.`

Specification forming part of Letters Patent No. 216,255, dated June l0, 1879; application iled December 10, 1878.

To all whom t may concern:

Be it known that I, CARL BRANDT, of the city of Goersnitz, in the Duchy of Saxe-Altenburg, German Empire, have invented certain Improvements in Buttons, of which the following is a specification.

The present invention relates to certain improvements in buttons designed for attachment to garments; and the object thereof is to protect and conceal the attaching thread, so as not to expose the same on the face of the button and render it liable to wear and discoloration. v

The present invention consists in a button having a concentric groove or channel in its front face extending obliquely from the edge of the button, and intersecting with two or more oblique openings leading to the rear face of the button. By the presence of the concentric oblique groove or channel a cone-shaped central portion of the button is formed, which serves to cover and protect the thread lyingV in th'e concentric groove.

In the accompanying drawings, forming part of this specification, Figure l is a front View of a button constructed according to my invention. Fig. 2 is a vertical section of the same, and Fig. 3 is a rear view thereof.

The body ofthe button is constructed of any suitable materialsuch as glass, porcelain,

, metal, or wood-and it is made of any preferred form or pattern. In the front face of the button is cut a concentric or circular groove or channel, b, which commences near the edge or rim of the button, and leads downward in an oblique direction to a sufficient depth-say, to the middle of the button. By the formation of this oblique and concentric groove an inverted-cone-shaped central portion, d, is provided, which serves to conceal and cover the thread lying in the bottom of said groove. The openings a (two or more) intersect with the groove or channel, and extend obliquely to the rear face of the button. The needle,

with its thread for attaching the button, isA readily passed into the concentric groove and the cone d, so to speak, and is not exposed to strain and wear. A small groove may be made in the rear face of the button for guiding the needle to the holes, as is shown in Fig. 3.

I am aware of the patent granted to P. E. Richardierre, and I desire to disclaimthe construction of button forming the subject-matter thereof. i

Having thus described my invention, what I claim as new7 and desire to see-ure by Letters Patent, is-

The button herein described, having a con` centric or circular groove, b, in its front face leading obliquely in a downward direction, the central cone'shaped portion, d, and the oblique outlet-openings a for the attaching-thread, as and for the purpose set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

CARL BRANDT.
